Pin Configuration and Functionality
/RSTHS (Reset input High side)
Function 1: Enable/shutdown of the input chip. (The IGBT is off if /RSTHS = low). A minimum pulse width is defined to
make the IC robust against glitches at INHS-.
Function 2: Resets the DESAT-FAULT-state of the chip if /RSTHS is low for a time T
. An internal Pull-Up-Resistor is
RST
used to ensure /FLTHS status output.
/FLTHS (Fault output High side)
Open-drain output to report a desaturation error of the IGBT (/FLTHS is low if desaturation occurs)
RDYHS (Ready status High side)
Open-drain output to report the correct operation of the device. (RDYHS = high if both chips are above the UVLO level and
the internal chip transmission is faultless)
VCC1HS (High side)
5V power supply of the input chip
VEE2HS (High side)
Negative power supply pins of the output chip. If no negative supply voltage is available, both pins have to be connected to
GND2HS.
DESATHS (Desaturation High side)
Monitoring of the IGBT saturation voltage (V
) to detect desaturation caused by short circuits. If OUT is high, V
is above
CE
CE
a defined value and a certain blanking time has expired, the desaturation protection is activated and the IGBT is switched off.
The blanking time is adjustable by an external capacitor.
CLAMPHS (Clamping)
Ties the gate voltage to ground after the IGBT has been switched off at a defined voltage to avoid a parasitic
switch-on of the IGBT.During turn-off, the gate voltage is monitored and the clamp output is activated when the
gate voltage goes below 2V (related to VEE2HS).
GND2HS (High side)
Reference ground of the output chip.
OUTHS (Driver output High side)
Output pin to drive an IGBT. The voltage is switched between VEE2HS and VCC2HS. In normal operating mode Vout is
controlled by INHS+, INHS- and /RSTHS. During error mode (UVLO, internal error or DESATHS Vout is set to VEE2HS
independent of the input control signals.
VCC2HS (High side)
Positive power supply pin of the output side.
GND1LS (Low side)
Ground connection of the input side.
INLS+ Non-inverting driver input (Low side)
INLS+ control signal for the driver output if INLS- is set to low. (The IGBT is on if INLS+ = high and INLS- = low)
